 ABC News. I'm Chuck Sievertson. Preps going on for tomorrow's first presidential debate, which will have no studio audience. And candidates Mike will only be on when it's his turn. ABC's Rachel Scott. Some advisors and some allies do acknowledge that they hope that this actually helps the former president stay on message because he won't have to play off the audience. He can control the message, control the narrative. But anybody that knows Donald Trump well knows that it will be up to Donald Trump. We don't necessarily know which version of the former president we are going to get tomorrow night on that.
